octacyanomolybdate(IV) anions‚ Mo(CN)84-‚ of approximate dodecahedral‚ D2d‚ and square antiprismatic‚ D4d‚ symmetry. The sensitivity of the Mo magnetic shielding (σ) and electric field gradient (EFG) tensors to small changes in the local structure of these anions allows the approximate D2d and D4d Mo(CN)84- anions to be readily distinguished. The use of high applied magnetic fields‚ 11.75‚ 17.63 and 21.1 T‚ amplifies the overall sensitivity of the NMR experiment and enables more accurate characterization

Magnetic Fields PHY 114 Lab Report 10/23/2013 Abstract: The purpose of this experiment was to surrounding a magnet there is a magnetic field. The magnetic field is analogous to the electric field that exists in the space around electric charges. Like the electric field‚ the magnetic field has both a magnitude and a direction. The direction of the magnetic field at any point in space is the direction indicated by the north pole of a small compass needle placed at that point. Since electric

Mohammed Alhallafi Professor Lidinsky Sept 10‚ 2012 "Two Ways a Woman Can Get Hurt": Advertising and Violence Jean Kilbourne in her article Two Ways a Woman Can Get Hurt says‚ ” Sex in advertising is pornographic because it dehumanizes and objectifies people‚ especially women‚ and because it fetishizes products‚ imbues them with an erotic charge- which dooms us to disappointment since products never can fulfill our sexual desires or meet our emotional needs" (459). Jean Kilbourne explains the

Latihan 5: Magnetism Magnetic Fields 1. An electron gun fires electrons into a magnetic field directed straight downward. Find the direction of the force exerted by the field on an electron for each of the following directions of the electron’s velocity: (a) horizontal and due north; (b) horizontal and 30° west of north; (c) due north‚ but at 30° below the horizontal; (d) straight upward. 2. (a) Find the direction of the force on a proton moving through the magnetic fields in Figure 1‚ as

BUSINESS 501 ETHICS The Case of the Mattel Toy Company According to the instructions for this case study‚ three virtues were to be chosen to identify with the case study. In keeping with the instructions‚ I have chosen Honesty‚ generosity and justice as the 3 virtues to associate with the case. Stanford Encyclopedia of Philosophy states‚ “A virtue such as honesty or generosity is not just a tendency to do what is honest or generous‚ nor is it to be helpfully specified as a “desirable” or “morally

TYPES OF MAGNETIC MATERIALS Paramagnetic materials have a small‚ positive susceptibility to magnetic fields. These materials are slightly attracted by a magnetic field and the material does not retain the magnetic properties when the external field is removed. Paramagnetic properties are due to the presence of some unpaired electrons‚ and from the realignment of the electron paths caused by the external magnetic field. Paramagnetic materials include magnesium‚ molybdenum‚ lithium‚ and tantalum

ABSTRACT Evolution of casting techniques can be classified into three generations. In the first and oldest generation mould is made by means of squeezing and jolting the green mould sand. In the second generation the organic binder are used to stabilize the moulding materials. In the third generation or the latest generation the physical means such as gravity‚ vacuum or magnetic field is used for stabilization of the free flowing dry moulding materials. The

Response to “Two Ways a Woman Can Get Hurt”: Advertising and Violence It is without a doubt that advertisement surrounds one’s life on a daily basis. According to Consumer Reports Website‚ the average American is exposed to 247 commercial messages each day. In the article “Two Ways a Woman Can Get Hurt” the author Jean Kilbourne strongly believes that advertising is one of the culprits behind the objectification and violence against women. Kilbourne points out that ads depict men and especially

Magnetic Susceptability Michael J. Horan II Abstract: The change in weight induced by a magnetic field for three solutions of complexes was recorded. The change in weight of a calibrating solution of 29.97% (W/W) of NiCl2 was recorded to calculate the apparatus constant as 5.7538. cv and cm for each solution was determined in order to calculate the number of unpaired electrons for each paramagnetic complex. Fe(NH4)2(SO4)26(H20) had 4 unpaired electrons‚ KMnO4 had zero unpaired electrons‚ and

MAGNETIC MAGNETIC REFRIGERATION a fruitful approach to reduce environmental pollution... ABSTRACT : The objective of this effort is to determine the feasibility of designing‚ fabricating and testing a sensor cooler‚ which uses solid materials as the refrigerant. These materials demonstrate the unique property known as the magneto caloric effect‚ which means that they increase and decrease in temperature when magnetized/demagnetized. This effect has been observed for many years and was used for cooling
